Abstract
The utility model relates to a pouring die for a part with an inwardly-sunken opening. The pouring die comprises an upper die, and a lower die with a cavity, wherein the upper die is positioned right above the lower die; at least two pouring gates opposite to the cavity is arranged on the upper die; a die core is arranged in the middle part; the lower half part of the die core is positioned in the cavity of the lower die; a pottery mud die insert is arranged at the outer part of the die core; an edge turning outwards is arranged at the joint of the upper die and the lower die; thread connecting holes are formed in the turning edges; bolts are connected in the thread connecting holes in a screwing manner; a thread hole is formed in the middle part of the upper die; an outer thread matched with the thread hole is arranged on the die core. According to the utility model, through adopting pottery mud as the die insert, the pouring die has the characteristics of high temperature resistance, corrosion resistance, good plasticity and capability of facilitating machining and shaping, and hardly reacts when being in contact with iron, steel and aluminium products, so that the mechanical property of the pouring die is unaffected, and moreover, the pouring die can be used in a recycling manner, therefore, the waste of resources is avoided and the processing cost is reduced.
Description
Technical field
The utility model relates to a kind of mould, relates in particular to a kind of inner recess part casting mold.
Background technology
In machine-building, often can run into concavo-convex product, as casing series products.Such shape of product is complicated, is mostly shaped as inner wide and outer narrow.Because the product difficulty of processing of concavity is large, the method generally adopting is at present sand casting, but because each chiltern casting mold can only be poured into a mould once, after acquisition foundry goods, casting mold damages, and moulding again, so the production efficiency of sand casting is lower; The porous because the bulk property of sand is soft again, so the casting dimension accuracy of sand casting is lower, surface is also more coarse.
There is at present a kind of Combined-type mould casting workbench, comprise lifting platform and be arranged at the mould on described lifting platform, described Combined-type mould casting workbench is arranged in vacuum environment, described Combined-type mould casting workbench also comprises the mixing cast structure of casting machine, described mixing cast structure is positioned at the top of described mould, described mould comprises upper die and lower die, between described upper die and lower die, form mold cavity, described upper die and lower die include internal layer soft mode and are coated on the outer die of described internal layer soft mode outside, described mold cavity is positioned at the idle area that internal layer soft mode joint forms.Although this Combined-type mould casting workbench can shorten the mould production cycle, improve the operating efficiency of rapid shaping processing, when guaranteeing mould and die accuracy, save the consumption of material, reduce production costs.But it can only process the part that inner chamber wall is vertical, for the part of inner wide and outer narrow, cannot process.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of inner recess part casting mold is provided, and it can process the part of inner wide and outer narrow, simple to operate and can recycle.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of inner recess part casting mold, comprise patrix and the counterdie that is provided with die cavity, described patrix be positioned at counterdie directly over, on described patrix, be provided with the cast gate over against die cavity, middle part is provided with core rod, and described core rod the latter half is positioned at counterdie die cavity, and its outer setting has pottery mud mold insert.
Preferably, described upper die and lower die joint is provided with outside flange, on described flange, is provided with threaded connection hole, is connected with bolt in threaded connection hole.
Preferably, described cast gate has two at least.
Preferably, on described patrix, middle part is provided with screwed hole, is provided with the external screw thread matching with screwed hole on core rod.
Compared with prior art, usefulness of the present utility model is: this inner recess part casting mold adopts pottery mud as mold insert, there is high temperature resistant, corrosion-resistant and good plasticity and be easy to the feature of machine-shaping, and running into iron, steel, aluminium material seldom reacts, can not affect its mechanical performance, and can be recycled, avoided the wasting of resources, reduced processing cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the utility model inner recess part casting mold structure cutaway view.
In figure: 1, patrix; 2, counterdie; 3, product; 4, pottery mud mold insert; 5, cast gate; 6, core rod; 7, pilot pin; 8, threaded connection hole.
The specific embodiment
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail:
A kind of inner recess part casting mold shown in Fig. 1, comprise patrix 1 and the counterdie 2 that is provided with die cavity, described patrix 1 be positioned at counterdie 2 directly over, described patrix 1 and counterdie 2 joints are provided with outside flange, on described flange, be provided with threaded connection hole 8, in threaded connection hole 8, be connected with bolt 7, on described patrix 1, be provided with the cast gate 5 over against die cavity, in order to guarantee that cast evenly, described cast gate 5 has two at least, described patrix 1 middle part is provided with core rod 6, this core rod 6 is connected with the screwed hole being arranged on patrix 1 by the external screw thread of end disposed thereon, described core rod 6 the latter halfs are positioned at counterdie 2 die cavities, and its outer setting has pottery mud mold insert 4.
Its specific works mode is as follows: when making cancavo-convex special shape products, first by core rod 6, the screw thread by its upper end is connected with the screwed hole of patrix 1, install core rod 6, then in the outer cover of core rod 6, connect according to the inner die cavity of product 3 and require to make pottery mud mold insert 4, then patrix 1 is arranged on counterdie 2, and by fixing by bolt 7 and threaded connection hole 8 riveted joints, subsequently potting syrup is evenly injected in the die cavity of counterdie 2 by the cast gate 5 on patrix 1, after product 3 die casts, the bolt 7 that connects patrix 1 and counterdie 2 is unloaded from threaded connection hole 8, patrix 1 and core rod 6 are taken out, then knock pottery mud mold insert 4, by product 3 demouldings, complete processing.
This inner recess part casting mold adopts pottery mud as mold insert, there is high temperature resistant, corrosion-resistant and good plasticity and be easy to the feature of machine-shaping, and running into iron, steel, aluminium material seldom reacts, can not affect its mechanical performance, and can be recycled, avoid the wasting of resources, reduced processing cost.
It is emphasized that: be only preferred embodiment of the present utility model above, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
